Enable-PSRemoting not found

One of our test users is reporting that on their test 2k8 system that when they run an elevated Powershell prompt Enable-PSRemoting is returning a 'is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again' message.

They are in the admins group and as I said the prompt is elevated, and the shell is on to the local computer.

Would anyone know of other things to search for please?

• It doesnt matter if the calling user has admin privileges, the cmdlet should be visible. You're probably not running PowerShell 2.0. You can download it here:

  Do you get any results when you run th following (no result means you're not running v2.0 or previous CTP versions:

  $PSVersionTable

  A typical result (on Windows 7 ) looks like:

  PS > $PSVersionTable
  
  Name                           Value
  ----                           -----

  BuildVersion                   6.1.7600.16385
  PSVersion                      2.0
  WSManStackVersion              2.0
